Description

[Technical Field]

[0001] The present invention relates to a cremation facility equipped with a lifting mechanism. [Background technology]

[0002] The cremation equipment described in Patent Document 1 is known to be equipped with a cremation chamber, an incineration stand that is placed in the cremation chamber and on which the cremated body is placed, an entrance / exit for the cremated body to be taken in and out of the incineration chamber, and a lifting mechanism for raising and lowering the incineration stand.

[0003] According to the cremation equipment in the above document, the cremated bodies are incinerated at a location away from the entrance / exit by raising and lowering the incineration table using the lifting mechanism, which prevents odors and heat caused by incineration from leaking to the outside. However, since the structure is designed for the incineration of a single cremated body, it has the disadvantage that it is difficult to efficiently incinerate multiple cremated bodies.

[0015] Fig. 1 is a longitudinal cross-sectional view of a cremation facility to which the present invention is applied, Fig. 2 is a longitudinal cross-sectional view showing the state in which the incineration table has been lowered by the lifting mechanism, and Fig. 3 is a plan view showing the configuration of the reburning chamber. The cremation facility shown in the figure is equipped with a main combustion chamber (cremation chamber) 2 for cremating the cremated body 1, which is the remains of a human or animal, etc., a cremation furnace 4 including a reburning chamber (combustion chamber) 3 that reburns and detoxifies the gas generated in the main combustion chamber 2, multiple incineration tables 6 on which the cremated body 1 is placed, a single entrance / exit 7 for taking the cremated body 1 in and out of the main combustion chamber 2, and a lifting mechanism 8 that supports the incineration table 6 so that it can be raised and lowered.

[0016] The crematorium 4 is a space formed into a rectangular parallelepiped that is long in the vertical direction by a ceiling 9, peripheral walls 11, and a floor 12, and the ceiling 9, peripheral walls 11, and floor 12 are made of insulating materials such as brick or ceramic. Within the crematorium 4, multiple main combustion chambers 2, 2 (two in this example) are arranged side by side in the vertical direction, and a reburning chamber 3 is arranged directly above the upper main combustion chamber 2. In addition, both main combustion chambers 2, 2 and the reburning chamber 3 are connected by a flue 13 provided within the crematorium 4.

[0017] Furthermore, the crematorium 4 has a lower structural part 14 extending between the two main combustion chambers 2, 2, and an upper structural part 16 extending between the upper main combustion chamber 2 and the reburning chamber 3. These structural parts 14, 16 divide the space inside the crematorium 4 into three levels in a side cross-sectional view, and these divided spaces are configured as the reburning chamber 3, the first main combustion chamber 2, and the second main combustion chamber 2 from the top.

[0018] In addition, both structural parts 14, 16 have a rectangular opening 18 formed in a plan view so that a lift 17 of the lifting mechanism 8, which will be described later, can pass through. In other words, the crematorium 4 has an open atrium where each floor from the second main combustion chamber 2 to the reburning chamber 3 is connected by the opening 18.

[0019] The first main combustion chamber 2 is a rectangular parallelepiped space with the longitudinal direction extending from the front to the back, and the aforementioned entrance / exit 7 is formed in the peripheral wall 11 on the front side, while a heating device 19 for cremation is located in the upper central part of the peripheral wall 11 on the back side. The first incinerator 6 is also located along the longitudinal direction.

[0020] The second main combustion chamber 2 is a rectangular parallelepiped space whose longitudinal direction is from the front to the back, and a cremation heating device 19 is located in the upper central part of the peripheral wall 11 on the back side. Also, the second incineration table 2 is located along the longitudinal direction. In other words, the incineration tables 6, 6 are provided in multiple levels, one above the other.

[0021] Each heating device 19, 19 is a burner 19, 19 that sprays a flame toward the cremated body 1 or the wooden coffin 21 in which the cremated body 1 is placed to incinerate the cremated body 1, and its base end is embedded in an arrangement hole 22, 22 formed in the peripheral wall 11 of the crematorium 4 and is supported by a swinging mechanism (not shown) so that it can swing up and down and left and right. By this swinging action, the burner 19, 19 is configured to be able to adjust the direction of the flame spray.

[0022] The entrance 7 is opened and closed by a fire door 23 located in front of it and configured to be able to open and close (raise and lower) by an operating mechanism (not shown). In addition, the cremated body 1 or the coffin 21 containing the cremated body 1 is taken in and out of the first main combustion chamber 2 through this entrance 7.

[0023] The first incinerator 6 is formed in the shape of a rectangular parallelepiped elongated in the longitudinal direction of the first main combustion chamber 2, and has a main body 24 with a mounting surface on its upper surface for placing the cremated body 1 or coffin 21, a plurality of running wheels 26, 26 formed symmetrically on the lower side of the main body 24, and a support part 27 provided for each running wheel 26 and rotatably supporting the running wheel 26. The first incinerator 6 is configured as a movable platform 6 that can be moved horizontally or in a direction along the horizontal direction by the running wheels 26.

[0024] The second incinerator 6 is formed in the shape of a rectangular parallelepiped elongated in the longitudinal direction of the second main combustion chamber 2, and has a main body 28 with a mounting surface on its upper surface for placing the cremated body 1 or coffin 21, a plurality of running wheels 29, 29 formed symmetrically on the lower side of the main body 28, and a support part 31 provided for each running wheel 29 and rotatably supporting the running wheel 29. The second incinerator 6 is configured as a movable base 6 that can be moved horizontally or in a direction along the horizontal direction by the running wheels 29.

[0025] Furthermore, both crematorium stands 6,6 are only required to be configured so that the cremated body 1 or coffin 21 can be placed on their placement surface. For example, they may not have running wheels 26,29 and support parts 27,31, but may be fixed stands 6,6 fixed to each main combustion chamber 2,2.

[0026] Next, the configuration of the lifting mechanism will be described with reference to FIGS.

[0027] The lifting mechanism 8 has a plurality of lifts 17 (two in this example) arranged side by side in the vertical direction, a pair of left and right lifting rails 32, 32 that support the lifts 17, 17 so that they can be raised and lowered, and a lifting actuator. The first incinerator 6 is placed on the upper surface of the upper lift 17, while the second incinerator 6 is placed on the upper surface of the lower lift 17.

[0028] The pair of lifting rails 32, 32 are track members made of a material with excellent heat resistance, such as ceramic, and extend vertically from the floor 12 of the crematorium (second main combustion chamber) 4 to the lower end of the upper structure 16, and are arranged so that the distance between them is the same as or approximately the same as the width (left-right length) of the lifts 17, 17 in a plan view. In addition, the lifting rails 32 are formed in a U-shape with the sides that approach each other being open in a plan view.

[0029] The lift 17 is a rectangular thick plate member made of a heat-resistant material such as ceramic, and has engaging portions 33, 33 that protrude symmetrically outward on the left and right sides in a plan view. The engaging portions 33, 33 engage with a pair of U-shaped lift rails 32, 32, allowing the lift 17 to move up and down along the lift rails 32.

[0030] The lifting actuator is an electric actuator that is operated by power supplied from an external source, and moves the lifts 17, 17 up and down based on a signal output from a control unit 34, which will be described later.

[0031] By raising the lifts 17, 17 arranged above and below with the lifting mechanism 8, the lower lift 17 is displaced to just above the lower structure 14 and raised to a height where the second incinerator 6 is located in front of the entrance / exit 7, while the upper lift 17 is displaced to just below the upper structure 16 and raised so that the first incinerator 6 is located in the reburning chamber 3. On the other hand, by lowering the lifts 17, 17 arranged above and below, the lower lift 17 is displaced to just above the floor 12 of the crematorium 4 and the second incinerator 6 is located in the second main combustion chamber 2, while the upper lift 17 is displaced to just above the lower structure 14 and lowered to a height where the first incinerator 6 is located in front of the entrance / exit 7.

[0032] As described above, by adopting a structure that allows the incineration table 6 to be positioned at the height of the entrance / exit 7 to be switched, different cremated bodies 1 or coffins 21 can be placed on each incineration table 6, 6 through a single entrance / exit 7.

[0033] The lift 17 may also be configured to have a pair of left and right guide rails 36, 36 laid in the front-to-rear direction on its upper surface. The guide rails 36 are formed in a concave shape when viewed from the front, and engage and support the running wheels 26, 29 so that they can rotate back and forth, thereby supporting the movable base 6 so that it can slide back and forth in the front-to-rear direction. This allows the movable base 6 to be easily moved in and out of the main combustion chamber 2 through the entrance 7.

[0034] Next, the configuration of the reburning chamber 3 and the smoke treatment will be explained based on Figures 1 to 4. Figure 4 is a block diagram showing the configuration of the smoke treatment. The reburning chamber 3 is provided with the outlet of the flue 13 described above, and the exhaust gas containing harmful substances generated in each main combustion chamber 2, 2 during the incineration process of the cremated body 1 flows into the reburning chamber 3 through the flue 13.

[0035] The re-burning chamber 3 is a rectangular parallelepiped space with the longitudinal direction extending from the front to the back, and includes a heating device 37 for re-burning, an opening and closing floor 38 configured to be able to be opened and closed, and an exhaust duct 39 that leads the exhaust gas that has been re-burned to the exhaust gas treatment chamber 42.

[0036] The re-burning heating device 37 is a burner 37 that performs re-burning by injecting a flame into the exhaust gas flowing into the re-burning chamber 3, and its base end is embedded in an arrangement hole 41 formed in the peripheral wall 11 of the crematorium 4, and is supported by a swinging mechanism (not shown) so that it can swing up and down and left and right. By this swinging action, the burner 37 is configured to be able to adjust the direction of the flame injection.

[0037] The opening and closing floor 38 is formed to be slightly thinner than the upper structure 16, is embedded in the upper structure 16, and is configured to be able to slide open and close in the left and right direction by an opening and closing mechanism (not shown). When the opening and closing floor 38 is in the open state, the opening 18 of the upper structure 16 is open, allowing the first incinerator 6, which is lifted by the lift 17, to enter the reburning chamber 3, while when switched to the closed state, the opening 18 of the upper structure 16 is closed.

[0038] The entrance of the smoke exhaust duct 39 is located at the front end of the ceiling 9 of the reburning chamber 3, and extends to a separately provided exhaust gas treatment chamber 42. The smoke exhaust duct 39 connects the reburning chamber 3 and the exhaust gas treatment chamber 42.

[0039] With the above-mentioned configuration, when the cremated body 1 is incinerated, the opening / closing floor 38 is switched to the closed state and the opening 18 is blocked, thereby preventing the exhaust gas from leaking into the main combustion chamber 2 through the opening 18 due to convection associated with the re-burning process.In addition, the exhaust gas that has been rendered harmless by the re-burning process can be introduced into the exhaust gas treatment chamber 42 through the exhaust flue 39.

[0040] The exhaust gas introduced into the exhaust gas treatment chamber 42 is cooled and dust-collected by the cooling device and dust collector installed in the exhaust gas treatment chamber 42, and is then exhausted to the outside of the cremation equipment through the exhaust port.

[0041] Next, the configuration of the control unit 34 will be described with reference to Fig. 5. Fig. 5 is a block diagram showing the configuration of the control unit.

[0042] The control unit 34 is connected on the input side to the operation panel 43. On the other hand, the burners 19, 19, 37, the lifting mechanism 8, the fire door 23, and the opening / closing floor 38 are connected on the output side.

[0043] The operation panel 43 has a start button for starting the cremation process, a forced stop button for terminating the process midway, and a display unit that displays various information about the cremation equipment, such as the temperature inside each main combustion chamber 2,2.

[0044] The control unit 34 is configured to execute an ignition process for igniting each burner 19, 19, 37, an oscillation process for oscillating each burner 19, 19, 37, an extinguishing process for extinguishing each burner 19, 19, 37, an adjustment process for adjusting the output of each burner 19, 19, 37, an ascent process for raising the lifting mechanism 8, a descent process for lowering the lifting mechanism 8, an opening process for raising the fire door 23, a closing process for lowering the fire door 23, a blocking process for switching the open-close floor 38 from an open state to a closed state, and an opening process for switching the closed-close floor 38 from a closed state to an open state.

[0045] To explain the cremation process in detail, the process begins when the start button is pressed. First, the raising process is performed, and the second incinerator 6 is positioned at a height that is directly in front of the entrance / exit 7. Next, the door opening process is performed, and the entrance / exit 7 is opened. At this time, the cremated body 1 or the coffin 21 is placed on the placement surface of the second incinerator 6.

[0046] After the cremated body 1 or coffin 21 is placed, the lowering process is carried out and the first crematorium stand 6 is positioned at a height in front of the entrance / exit 7, and the cremated body 1 or coffin 21 is placed on the placement surface in the same way. After it is confirmed that the cremated body 1 or coffin 21 is placed on each crematorium stand 6, 6, the door closing process is carried out and the entrance / exit 7 is closed.

[0047] After it is confirmed that the entrance 7 is closed, a closing process is carried out, and the opening 18 of the upper structure 16 is closed by the opening / closing floor 38 that has been switched to the closed state.

[0048] Then, the ignition process is carried out, and the cremated body 1 is incinerated by each burner 19, 19, 37, and the re-burning process is carried out in the re-burning chamber 3. The rocking process is carried out as appropriate when there is a bias in the heating area, and the adjustment process is carried out as appropriate so that the internal temperature of each main combustion chamber 2, 2 and re-burning chamber 3 is kept at 800 ° C to 1000 ° C.

[0049] When the incineration and re-burning processes are completed, the fire extinguishing process is carried out. After it is confirmed that each incineration rack 6, 6 has cooled down to a temperature at which it can be removed, the door opening process is carried out, and the cremated body 1 placed on the first incineration rack 6 is removed through the entrance 7. Next, the lifting process is carried out, and the cremated body 1 placed on the second incineration rack 6 is similarly removed.

[0050] After each cremated body 1,1 is removed, the door is closed, completing the cremation process.

[0051] According to the cremation equipment configured as described above, multiple cremated bodies 1,1 can be transported into the cremation chamber 2,2 through a single entrance / exit 7 and incinerated in parallel, so the incineration work of multiple cremated bodies 1,1 can be carried out more efficiently.

[0052] Next, another embodiment of the present invention will be described with reference to Figures 6 to 8. Figure 6 is a side cross-sectional view of a cremation facility according to another embodiment of the present invention, Figure 7 is a side cross-sectional view showing the cremation furnace raised by the lifting mechanism, and Figure 8 is a block diagram showing the configuration of the smoke exhaust treatment system of the cremation facility shown in Figure 6.

[0053] The cremation equipment in the above-mentioned form was configured to include two main combustion chambers 2, 2 arranged side by side in the vertical direction inside the crematorium 4, a reburning chamber 3 arranged directly above them, and a lifting mechanism 8 provided inside the crematorium 4. However, the cremation equipment in this form has a space S1 formed by being surrounded by an insulating wall 44, a single main combustion chamber 2, and a reburning chamber 3 arranged directly above it, and is also equipped with multiple crematoriums 4, 4 housed in the space S1, and a lifting mechanism 8 arranged below the crematorium 4. The crematoriums 4, 4 are arranged side by side in the vertical direction, and the lifting mechanism 8 is configured to raise and lower the multiple crematoriums 4, 4 as a whole.

[0054] In addition, it differs from the above-mentioned configuration in that the entrance / exit 7 is formed as an opening in the insulating wall 44 toward the front, that each main combustion chamber 2,2 is provided with a separate entrance / exit 7,7 and fire doors 23,23, and that the entrances to the smoke exhaust duct 39 are provided separately in the reburning chambers 3,3 of both crematoriums 4,4, and that the flow paths are configured to merge halfway through.

[0055] According to the cremation equipment configured as described above, the lifting mechanism 8 is located outside the crematorium furnace 4, so the lifting mechanism 8 is not exposed to high temperatures during the incineration process, which extends its service life.In addition, since the structure of the opening and closing floor 38 is omitted, a simpler structure can be achieved.

[0056] Next, another embodiment of the present invention will be described with reference to Figure 9, showing the differences from the above embodiment. Figure 9 is a side cross-sectional view of a cremation facility according to another embodiment of the present invention. This embodiment comprises a single main combustion chamber 2 and a support frame 46 that is arranged in the main combustion chamber 2 and to which multiple incineration stands 6, 6 are attached and supported, and the lifting mechanism 8 is configured to lift and lower the support frame 46 together with the multiple upper and lower incineration stands 6, 6 attached and supported thereto.

[0057] The support frame 46 is formed in a box shape and has a plurality of storage spaces S2, S3 arranged side by side in the vertical direction. The incineration stands 6, 6 are arranged in each of these storage spaces S2, S3 and are detachably attached to the support frame 46 by mounting members.

[0058] According to the cremation equipment configured as described above, the main combustion chamber 2 is a single unit, which allows for a simpler structure.In addition, the lifting mechanism 8 is designed to lift and lower only the support frame 46 and the incineration table 6, and there is no need to lift and lower heavy objects such as the main combustion chamber 2, which reduces the load on the lifting mechanism 8.

[0059] In the example described above, two incineration stands 6 are arranged vertically, but three or more incineration stands 6 may be arranged vertically. These three or more incineration stands 6 arranged vertically are raised and lowered together within the main combustion chamber 2 by the lifting mechanism 8. [Explanation of symbols]
